, SPECIFICATION forming part of Letters Patent No. 743,864, datedNovember 10, 1903.

Application filed April 20, 1903.

To a/ZZ whom, L'U' ntcty concern:

Beit known that I, EDWIN R. HALEsWon'rH, a citizen of the United States,residing at San Bernardino, in thecounty of San Bernardino and State ofCalifornia, have invented a new and useful Adjustable Locomotive-Pilotand Draw-Bar, of which the following is a specification.

My invention relates to improvements in the means for supportinglocomotivelplots and in improved construction of the draw-bar and itsconnection with the pilot and in details of construction of parts of thedraw-bar and pilot, which will be fully described here-v inafter.

The objects of my invention are to provide new and improved means foradjustably attachin g the pilot to the pilot-beam and to provide new andimproved construction of parts of the pilot and draw-bar.

The accompanying drawings illustrate the invention, and referring to thesame, Figure I is a vertical sectional view taken longitudinally throughthe pilot. Fig. II is a side elevation of the pilot. Fig. III is a planview of the pilot. Fig. IV is a sectional detail taken verticallythrough the pilot-beam and shows a portion of one of thepilot-standards. Fig. V is a front elevation 'of the Vsanne with the nutremoved and the attaching-bolt shown in section. FigVI is a detail ofthe improved turnbnckle. Fig. VII is a front elevation of the draw-barcasting attached to a portion of the pilot-beam with thepilot-supporting straps attached thereto. Fig.v VIII is a plan view ofmy improved turnbuckle.

1 designatesthe usual pilot-beam, to which is attached the'draw-barcasting 2,' the latter being formed with a base 3, which abuts againstthe front face of the pilot-beam 1 and from which forwardly project apair of wings 4, which are united at the bottom by a Wall 5. Projectingrearwardly from the upper edge fromrlthebaserS is a, bracket 7, whichlies upon the top face Vof the pilot-beam l1, the

drawbar casting Zbeing fastened to the pi-v lot-.beam by means of boltsS, which pass through the bracket 7.

9 designates the draw-bar, which on the lower side of its rear end isprovided with a lug 10. The lug 10 is rounded except for its forwardface, which is flat.

the pilot-beam V1. 'standards 16 and secure the proper positionsentiraresale. on man.)

opening formed by cutting away the wall 5 nea-r the base 3. In order toform a bearing against which the shoe 1l may draw, I provide anothershoe l2, which is bolted, preferably, to the under side of the wall 5and has4 a concave rear face against which the convex face of the lug 11bears when the drawvbar 9 receives the tensile strain.

The draw-bar 9 is pivotally attached to the wings et by means of a bolt13, which passes through the wings 4 and through an elongated slot ljlintheLdraw-bar 9. Interposed betwebieach wing 4 and the draw-bar 9 arecoil compression-springs l5, the width of the draw-bar being somewhatless than the space between the wings 4. The length of the slot 14 isenough to allow for sufficient play of the draw-bar, and it will beobserved that the draft does not come upon the bolt 13, but is taken upby the shoes .12 and 1l. The rear end of the draw-bar lies very close tothe base 3, and the object in forming the lug 10 undercut at its rearportion is to allow the drawbar to vbe tilted. By making the shoes 11and 12 removable they may be replaced by new shoes when they become soworn as to unfit them for use.

The pilot may be partially carried by standards 16, whichl may extenddownwardly from In order to adjust the ing of the pilot, I provide theupper end of each standard 16 with an elongated slot 17. In the slots 17are inserted plugs 18, which lie above and below the bolts 19, which se-Ecure the standards 16 to the pilot-beam 1.

When the pilot sags and 4it is wished tn raise or lower the same, one orthe other of the plugs 18 in each slot may readily be removed and thestandards 16 slipped up or down', as the case may be, after which newplugs may be readily inserted to lill the gaps between the bolts 19 andthe remaining plugs, after IOO which the nut may be screwed down. toforein adjusting the pilot-frame it has been necessary to remove thestandards 16, plug the old holes, and bore new holes, and this requiredthe use of tools and occasioned considerable inconvenience. It willreadily be seen that with the present construction the .adjusting of thepilot is accomplished quickly bar casting with a base 3, havingelongated slots 20, through which bolts 2l pass. By loosening the bolts2l and S the draw-bar casting may be raised and a shim placed under thebracket 7. The slots 20 allow for the raising of the draw-bar, afterwhich the bolts 2l and S may be tightened. In order to further supportthe bottom frame of the pilot, I provide a pair ot' straps 22, which maybe held in place by the bolts 2l and which may extend down and beattached to uprights 23 of the pilot-frame by means of bolts 24, whichmay pass through elongated slots 25 in the straps 22. The slotted endsof the straps 22 allow of an adjustment of the rear end ofthepilot-frame relatively to the straps 22. The straps 22 also provide asolid full face, against which the nuts of the bolts 21 take, the straps22 covering the slots 20.

In order to support the nose of the pilot, I provide a nose-brace 26,the lower front end of which may be hooked to an eyebolt 6. The upperrear end of the nose-brace will be connected by a hooked rod 27 with oneof the bolts 2l. In order to adj ust the length of the nose-brace 26, Iprovide a novel turnbuckle. One end of the nose brace rod 26 passesloosely through a yoke-frame 29 and is provided with threads whichengage a nut 30,.

which is held loosely in the yoke-frame 29. The other end of the frameis drilled and receives loosely the threaded end of the rod 27. 3l is anut inside of the yokeframe and mounted on the threaded end of the rod27. 32 is a set-nut on the rod 27. It will be seen that the threads arenot formed in the frame 29, as is usual in the ordinary turnbuckles, butthat the rods pass loosely therethrough. Therefore by loosening the nuts3l and 32 it is possible to quickly shift the frame 29 along the rods.The set-nuts may be run back from the frame 29, and as the sides of theyoke-frame 29 lie over the faces of the nuts 30 and 3l they act as awrench to turn the nuts, so that the nose-brace is tightened by merelyturning the yoke-frame 29. The nuts 30 and 3l have right and leftthreads.

In order to hold the draw-bar in a horizontal position, I provide a pin33, which passes Herethrough the wings 4 and lies over the top of thedraw-bar.

IVhen the draw-bar is not being used, the pin 33 may be withdrawn andthe draw-bar may be dropped into the position shown in Fig. II, so thatit rests between the mid-ribs of the pilot.

In order to cover the space between the mid-ribs of the pilot, I providegates 34, each of which consists of a pair of slats carried by rods 35,the slats being spaced apart by wooden washers 36.

37 designates hinges, which carry the gates and are mounted on themid-ribs.

rlhe gates may be swung back to allow the draw-bar to be dropped .intoplace, after which they may be closed-over the space and cover thedraw-bar.
